Solar cell module production process

Line called packaging line components, packaging is the production of solar cells a key step in the packaging process without a good, multi-well battery is also not a good component of production boards. Battery package not only the battery life is guaranteed, but also to enhance the combat strength of the battery. Product quality and high service life is to win can be the key to customer satisfaction, so the quality of components of the package board is very important.  

 

Process is as follows:  

1, the battery test

2, positive Welding - Inspection –

3, on the back of cascading - Inspection –

4, laying (glass cleaning, material cutting, glass pre-processing, laying) –

5, laminating –

6, to flash ( to the side, cleaning) –

7, fitted border (glue, loading angle keys, punching, install box, scrub I glue) –

8, the welding junction box –

Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
Q:solar panel for 2 batteries(2 V)?
0 of the panels wired in parrell will give you enough power to trickle charge the batteries. You will need a charge controller to prevent a overcharge from damaging your batteries. A panel array that is rated at 2 volts actually puts out a unregulated voltage up to 2 volts. I have bought some charger controllers from OKorder at good prices. They will also prevent the discharge of your batteries at night or when the panels are in the shade. If the panels only put out 5 volts they will not charge the batteries. Check each panel outside in the sun with a DC volt meter for proper operation before connecting them.
Q:Why are solar panels only 0% efficient?
Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.
Q:how instal solar panel?
There are MANY garden lights with built in batteries and solar panels that you just need to stick in the ground. There are also self contained units that are wall mountable. THAT way there is no need to run wiring, use battery stacks, etc. and will also probably be less expensive overall.
Q:can a small solar panel be charged with lamps?
Sure!...did you ever use a solar powered calculator indoors under a lamp?? It works just fine.
Q:How do you install solar panels?
This is still not a trivial project, although it is getting easier. The usual way to do this is to contact professional installers for free quotes. In the process of getting the quote, you'll learn what considerations go into sizing a solar system. They'll look at your energy usage, and also whether your house has a good, clear, south-facing roof that doesn't get shaded during the day. They'll also look at your electrical panel to see whether they can hook right up, or additional work is needed. There are rumors of companies like Akeena planning to sell panel kits in Home Depot (in areas that Akeena does not directly serve). The idea would be that a pro installer would pick up the kit there, but a highly skilled homeowner might be able to make it work. A permit will probably be required by your jurisdiction, but that's no different than applying for any other construction. And you'll have to inform your power utility in advance, which may or may not be routine, depending on how often people connect solar in your area. If you want to see how we connected our system, a link is below. I did not really save money by doing it myself. That's because pro's can get better prices on the panels, which makes up for the labor cost.
Q:Need help with a solar panel?
In order: .  Just about any wire will do.  You can handle 50 mA over just about anything, even 28 gauge telephone wire.  Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.  You need a diode.  If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.  The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.  You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.  This gives you maximum current output from your panel.
Q:Is using a thick cardboard backing for a solar panel ok?
No,do not use card board because your cells are quite powerful. Accident short might cause fire. Replace it with another piece of plexi-glass.
Q:SOLAR PANELS (sun enerjy)?
Grid-tied solar systems in the U.S. run at least $8/watt installed. To completely run a 2,000 sq ft home, you'd need about 50 amps service from solar -- both 20 volts and 240 volts. Not very practical. Panels are expensive, but the BOS (balance of system) is as well. You need mounts to bolt the panels to the roof (same thing if ground mounted). Cable, wire, and connectors will run several hundred dollars. A couple of grid-tie inverters in the range of 4,000 watts each will cost you several $6,000 to $8,000, plus sub panels, combiner boxes, breakers, disconnects, charge controls, and batteries, among other things. You'd likely need 5 to 24 panels, depending on too many factors to mention here. You'd need at least 8 batteries, likely 2 volt ones, probably more if you want to run the entire home from solar. Solar (or wind) systems have to be installed in the U.S. by state licensed installers, and there are not many of those yet. And if you grid-tie the system, you'll need to put an interconnection agreement in place with your local utility, plus the utility will have requirements on the net-metering and installation of a switch they can use to turn your solar system off from the grid. And this would not produce hot water in the way you are thinking. If you have an electric hot water heater now, the solar system could help run that, just like the rest of your home. Hot water from solar and electricity from solar are two completely different technologies.
Q:Where can i find a list of solar panel manufactures worldwide?
Actually Ofir, it is much easier and less expensive than you might believe. What you need is a magazine, like, Solar Today. There is only one that I am familiar with that gets into the nuts and bolts of solar panel manufacturers, installation, and other types of renewable energy. It's called, Home Power Magazine. We have a home that has been powered by the wind and sun for the last 0 years or so, and most of our initial information came from Home Power, and afterward, from many of the sources that they have in their articles. Every few issures, they take an item connected to renewable energy, such as an inverter, wind turbine, water turbine, or solar panel, and list all the different models that are available. They are broken down by manufacturer, and include specifications like power output, range of voltages, efficiency, materials, and even where they are manufactured. If you subscribe online for one year, the cost is around $25 USD, you will have access to all the previous issues that are archived on their website. You can use their search engine to locate an article listing all the solar panels, they did one a year or so ago with all the information you are looking for. Despite what you might be hearing, solar power usage is growing at an incredible rate. In the US alone, there are over 00,000 homes and businesses operating some level of solar power right now, that's good news. As far as different countries using different requirements, most all of the manufacturers today are selling their products to most countries worldwide, they are designed to meet requirements for almost anyplace you might use them. Check the magazine out today, you might learn more than you were originally looking for. I will include their link below, and some other good sources for information. You can google any one of them to find their website. Good luck, and take care...Rudydoo
